Limits at Infinity & Horizontal Asymptotes

Limits At Infinity

This video covers what to do if X is approaching infinity (or negative infinity) in lots of different situations: polynomial fractions, complex fractions, polynomials. I'll also show you a great trick that will cut your factoring time by 90% for these problems!

Using Limits To Find Horizontal Asymptotes

Yep, that's what we'll do. We'll also briefly review the pre-calc way of finding horizontal asymptotes of rational functions, first covered way back when in Pre-Calc.
